#### Sample Teach Path - Adaptive Free Form Plane Scan Strategy

This example of the teach path method for the Adaptive Free Form Plane Scan strategy shows a detailed procedure for scanning the top surface along a specific path.

In this example, suppose that you want to scan the top surface along the path shown below:

Scan path

To generate this path, take the hits to define the points as described below. The points are recorded in the list of point on the Path Definition tab. They are marked on the CAD as shown in the procedure.

1. The first segment in the path is linear. To generate this line:

   1. Select the button.

   2. Because this is the first segment, take two hits to define points 1 and 2 for the line.

2. The second segment in the path is also linear. Point 2 (the last point of the first segment line) is the start point of the second segment line. To generate this line:

   1. Keep the button selected.

   2. Take one hit to define point 3, the end point of the line for the second segment.

3. The third segment in the scan path is an arc along the big circle. Point 3 (the last point of the second segment line) is the start point of the arc. The last point is the end point of the arc. To generate this arc:

   1. Select the button.

   2. Take two more hits on the arc to define points 4 and 5.

4. The fourth segment is a line. The end point of the arc becomes the start point of the line. To generate this line:

   1. Select the button.

   2. Take one hit to define point 6, the end point of the line for the fourth segment.

5. You now need to scan 360 degrees around the small circle. The end point of the line of the fourth segment becomes the start point of the circle. To generate this circle:

   1. Select the button.

   2. Take two more hits to define points 7 and 8 for the circular path. Because a circle is 360 degrees, point 9 - the end point of the circle - is automatically recorded at the same location as the start point of the circle.

6. The last segment is a line. Point 9, the end point of the circle, becomes the start point of the line. To generate this line:

   1. Select the button.

   2. Take the last hit to define point 10, which completes the scan path.

7. Select the >> button. In the Teach Controls area, in the Increment box, type 1.

8. Click Generate. The generated scan path appears in the Graphic Display window.
